UBC will integrate the charts with its entertainment news sales offering into a lifestyle and entertainment sales unit.
Simon Cole, chief executive of UBC Media, said: "These are significant contract wins for us, and further endorsement of the success of our network radio sales division.
"Combining our entertainment news network with 'The A-List' and 'Fresh 40' provides advertisers with a great opportunity to reach over 11m adults within compelling and exciting programming."
'The A-List' has recently been sponsored by drinks brand Baileys and 'Fresh 40' by the government's drugs advice service Frank.
